I have a asp.net website and in the masterpage I have some dropdown controls where the user selects criteria for products. After the last selected dropdown box I send the selected values to another page which is child to masterpage and I make a query to the database and present the results in a gridview.
My problem is that the masterpage is refreshed and all the selected values are cleared. How can I keep the values to masterpage dropdown boxes or is there any better solution for this?
I've added an invisible Panel in the Masterpage and hide all the controls inside. Instead of posting to another page i'm filling the controls with the data and reveal the Panel. I found that this is faster and easier. Thanks for your help
